Sperm have tails and swim from the vagina through the uterus up to the oviduct. The egg and sperm join up in the oviduct. This is called FERTILISAT . Only one sperm is required to fertilise an egg. A fertilised egg travels down the oviduct to the uterus where it grows into a baby. OVARY PENIS FERTILISATION ONE OVIDUCT
